Wiring for VT Ecotec Engine Power
I'm fitting a 3.8 VT Ecotec to a Triumph TR7, and can't work out where the power supply for the ECM, Injectors, coils etc. comes from.
I'm guessing it is via the three plugs near the brake booster, but can't find a pin-out for them.
Does anybody have the pin-outs, or can tell me what to connect up.
I have the VATS disabled.

Re: Wiring for VT Ecotec Engine Power
Its the 6 pin rectangular plug near the booster. Red with black stripe is constant power from battery, red is switched power via relay via the ignition switch. Make sure they are fused.
There is more there like fan, temp gauge, oil light etc. I haven't got an ecotec diagram but I'm pretty sure the colours are mostly the same from the earlier models.

Re: Wiring for VT Ecotec Engine Power
I'm connecting the EcoTec wiring from the three plugs near the firewall, and trying to work out
which way the Fuel Pump Wire and Fan Switch wire work.
I thought the ECU would ground these wires, but the wiring diagrams seem to indicate that it
supplies power to switch the relay.
Do they supply 12v to switch the relays, or do they ground the relay switch circuit to turn it on.

Re: Wiring for VT Ecotec Engine Power
Not sure about ecotec but earlier engines have the fan relay grounded by the ECU and the fuel pump is powered by the ECU.

Also true for VX, so probably all Ecotecs.vlad01 wrote:Not sure about ecotec but earlier engines have the fan relay grounded by the ECU and the fuel pump is powered by the ECU.

Re: Wiring for VT Ecotec Engine Power
Fuel pump should be the only positive switched output if I remember correct
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem

Re: Wiring for VT Ecotec Engine Power
The Auto gearbox that I have doesn't have a Neutral/Safety switch, and there doesn't look to be enough
shaft protruding from the case to fit one.
It's a 4L60E box, with a 7HDD sticker, and 18 cast into the case, supposedly removed from a VS Commodore.
Did all 4L60E boxes have a Safety/Neutral switch, and are there different types for the earlier/later boxes.
The wiring loom I have has provision for a Neutral/Safety switch....is this going to cause problems?
